摘要:

在过去的二十年里,手征有效场论已经被证明是一个系统的、与模型无关的研究核力的有力工具。两个,三个,和四个核子力已经推导出次到主导阶(N3 LO),并(部分)应用于核少体和多体系统-一般来说,取得了很大的成功。这可能意味着我们终于解决了核力问题;但这将过于乐观。仍然有一些相当基本的悬而未决的问题,已经被扫到地毯下,最后,需要我们的全力关注,如双核子势的适当重整化。此外,多体力贡献的逐阶收敛在此时充其量是模糊的。

英文摘要:

During the past two decades, it has been demonstrated that chiral effective field theory represents a powerful tool to deal with nuclear forces in a systematic and model-independent way. Two-, three-, and four-nucleon forces have been derived up to next-to-next-to-next-to-leading order (N3LO) and (partially) applied in nuclear few- and many-body systems---with, in general, a good deal of success. This may suggest that we are finally done with the nuclear force problem; but that would be too optimistic. There are still some pretty basic open issues that have been swept under rug and, finally, need our full attention, like the proper renormalization of the two-nucleon potential. Moreover, the order-by-order convergence of the many-body force contributions is at best obscure at this time.
